E-liquids are the foundation of any great vaping experience. Whether you’re using compact pod kits or powerful sub-ohm devices, knowing how to use e-liquid correctly helps you get better flavour, smoother vapour, and longer coil life. This UK guide explains how to use e-liquids properly, with a special focus on popular brands such as Hayati Pro Max E-Liquid, Signature E-Liquid, Doozy Vape Co, Nasty Juice, Kingston Chill, Kingston Gazillions100ml shortfill, Ruthless, Seriously Slushy, and Loaded 100ml shortfills.

What Is E-Liquid?

E-liquid (also called vape juice) is the liquid heated by your vape device to produce vapour. Most UK e-liquids contain:

• Vegetable Glycerine (VG) – vapour production
  
  

• Propylene Glycol (PG) – flavour and throat hit
  
  

• Food-grade flavourings
  
  

• Nicotine (optional)
  
  

All nicotine-containing e-liquids sold in the UK comply with TPD regulations, with a maximum nicotine strength of 20mg.

What Is a 100ml Shortfill?

A 100ml shortfill is a large bottle of nicotine-free e-liquid with space left to add nicotine shots. This format is extremely popular among sub-ohm vapers who prefer lower nicotine levels and bigger clouds.

Most 100ml shortfills are 70VG/30PG, making them ideal for high-wattage vape kits.

How to Use 100ml Shortfill E-Liquids

Step 1: Add Nicotine Shots (Optional)

To turn a 100ml shortfill into a nicotine e-liquid:

• Add two 10ml nicotine shots (usually 18mg each)
  
  

• This creates approximately 120ml of 3mg e-liquid
  
  

If you vape nicotine-free, you can use the shortfill as it is.

Step 2: Shake Thoroughly

After adding nicotine shots, shake the bottle well for at least 1–2 minutes to ensure even nicotine distribution.

Step 3: Fill Your Tank

• Open your vape tank’s fill port
  
  

• Pour the e-liquid slowly to avoid spills
  
  

• Do not overfill
  
  

Always wipe excess liquid before closing.

Step 4: Prime the Coil

Let the e-liquid soak into the coil for 5–10 minutes before vaping to prevent dry hits.
